 * There is a compatibility issue with this plugin and Simple Calendar. They have
   updated Guzzlehttp, but this plugin is still on an older version. It throws a
   Critical Error 500 when both plugins are enable on whatever page the Simple Calendar
   is on. When I disable your plugin is resolves the issues. The Simple Calendar
   dev has been contacted and a topic posted [https://wordpress.org/support/topic/update-to-3-1-33-broke-my-site/](https://wordpress.org/support/topic/update-to-3-1-33-broke-my-site/).
   We are having to rollback our version of their plugin to get it to not crash 
   our sites. Can you please look at updating? Thanks!

 * This is due to unscoped dependencies.
    The same happend to WooCommerce + WP-Rocket
   too.
 * Please developers, always scope your (composer) dependencies.
    Multiple vendor
   folders and same classes will always conflict due to different implementations
   and interfaces.

 * php-scoper and other alternative solutions for WordPress should be used to prevent
   this.

 * Hello [@mkornegay2](https://wordpress.org/support/users/mkornegay2/) & @danielrufde,
 * Thanks for letting us know.
    We are actively working on scoping all dependencies
   in our plugins to resolve conflicts like this once and for all. Since we are 
   implementing this change in a variety of plugins, it will require a little bit
   of time. We appreciate you reaching out and will keep you updated regarding this
   issue.
 * Kind regards,
    Niklas

 * I echo [@ignaciojesus](https://wordpress.org/support/users/ignaciojesus/) here…
 * We’d love to hear as we’re still forced to run old code (older version of Simple
   Calendar) until this is fixed.
 * Could you update us please?
    Cheers!
